getLabel
Description copied from interface:Literal
Gets the label (the lexical value) of this literal.- Returns:
- The literal's label.
-
getLanguage
Description copied from interface:Literal
Gets the language tag for this literal, normalized to lower case.- Returns:
- The language tag for this literal, or
Optional.empty()
if it doesn't have one.
-
getDatatype
Description copied from interface:Literal
Gets the datatype for this literal.If
Literal.getLanguage()
returns a non-empty value than this must returnrdf:langString
. If no datatype was assigned to this literal by the creator, then this method must returnxsd:string
.- Returns:
- The datatype for this literal.
-
temporalAmountValue
Description copied from interface:Literal
Retrieves thetemporal amount
value of this literal.A temporal amount representation can be given for literals whose label conforms to the syntax of the XML Schema 2 xsd:duration datatype.
The adoption of the XML Schema 2 definition is a known deviation from the RDF 1.1 standard; well-formedness rules are relaxed to consider all duration components as optional and freely mixable.
Temporal amount representations may be converted to specific
java.time
values likeDuration
using target static factory methods, for instanceDuration.from(literal.temporalAmountValue())
.Note however that
java.time
doesn't include dedicated classes for legal XML Schema duration values including both date and time components (for instance,P1YT23H
).- Specified by:
temporalAmountValue
in interfaceLiteral
- Overrides:
temporalAmountValue
in classAbstractLiteral
- Returns:
- the temporal amount value of this literal
- Throws:
DateTimeException
- if this literal cannot be represented by aTemporalAmount
value- See Also:

getCoreDatatype
Description copied from interface:Literal
CoreDatatype is an interface for natively supported datatypes in RDF4J. This includes, among others, the XML Schema datatypes and rdf:langString. CoreDatatypes are implemented as enums and more performant and convenient to work with than IRI-based datatypes. The constantinvalid @link
{@link CoreDatatype#NONE)
- Returns:
- The CoreDatatype or
invalid @link
{@link CoreDatatype#NONE)
